K20D pic vertical line problem

Dear All,

I have taken some trial shoots with my new lens this morning, and found one pic has a vertical line, please see the 100% cropped photo attached. It appears in this photo only.

But I am still wondering if this shows a sign that the CCD may have problems?

The lens is F100mm/f2.8 macro, shot at 1/125 sec, f/2.8 and iso100.

Thanks!

-Jiang

Odd. I have the same camera and lens, and have never had that happen. Once, however when I was still using my ancient Minolta A1 prosumer camera, lines started appearing at random, and then a LOT, and then the sensor died!
In that case, fortunately, Sony replaced the 5mp sensor in a class action lawsuit...
Er, but I doubt it's your sensor going TU... Gamma ray burst?

The sensor is stitched (at least as far as I know, the K-7 had this exact same problem, although not nearly as severe), so this probably has something to do with that, considering that the line is directly in the middle of your photo.

I would just say send it in if it keeps doing it, try different subjects and scenes and see if you can find it.

The line isn't actually in the center. My calipers measure it 323 pixels from the left and 412 pixels from the right. With that in mind and the fact it happened on only one photo I think it is probably an SD card problem.

To be pedantic, the K10D has a CCD sensor, the K20D has a CMOS sensor.
